CLIP FOR LOOSE-LEAF BINDERS.

Application filed March 19, 1926. Serial No. 96,013.

This invention has relation to loose leaf binders and has particularreference to an improvement in the devices for connecting the leaveswith the binder back.

One of the principal and outstanding objects 0f the present inventionresides in the provision of a clip for connecting` the leaves v with thebinder back, which clip is detachably associated with the back to permitof its removal therefrom and association with another back.

The invention furthermore comprehends a clip for loose leaf binderswhich is comparatively simple, strong and durable in its construction,inexpensive to manufacture, and which is highly efficient in itspurpose.

`With the above recited and other objects in view, reference is had tothe following specification and accompanying drawings in which there isexhibited one example or embodiment of the invention which is in no wayintended as a limitation upon the scope of the appended claims as it isto be clearly understood that variations and modifications whichproperly fall within the scope of said claims may be resorted to whenfound expedient.

In the drawings-v Figure 1 is a sectional view illustrating the clip inassociated relation with the leaves and back of a loose-leaf binder;

Fig. 2 is a fragmentary view illustrating the clip in opened condition;

Fig. 3 is a detail sectional view taken approximately on the line 3 3 ofFig. 1.

Referring to the drawings by characters of reference, A designates thebinder back; B the leaves which are apertured or perforated at C, and I)the clip which comprises a base 10, the marginal or peripheral edge 11of which is rolled over a flexible plate or diaphragm 12 to secure thesame to the base. The plate or diaphragm 12 is formed with asubstantially medial slot 13 and portions of the plate adjacent theouter en'd of the slot are upwardly offset at 14: to receive andaccommodate laterally projecting trunnions 15 at one end of a hook orsplit ring member .16, so that the plate or diaphragm 12 will functiondue to its inherent resiliency to retain the opposite free end 17 of thehook or split ring member 16 in either a closed engaging position withthe plate as illustrated in F ig. 1, or in an open position with respectthereto as illustrated in. F ig. 2.

Iii-order to detachably associate the clip with the binder back A,whereby a clip of this structure may be interchangeably associated withbinder backs, the base 10 of each clip is formed with a projectingsubstantially spherical stud 18 which is 'designed to be insertedthrough a keeper opening 19 in the binder back, a receiving and engaginghead 20 being provided for frictionally connecting the head with thestud to detachably associate the clip with the binder back.

F rom the foregoing numerous advantages are apparent such as the removaland re-use of the clips with a new binder back after one binder back hasbecome worn or unfit for use, or the removal of the clips with the pagesappliedffroin one binder back and the insertion of the same in anotherbinder back so as to transfer the sheets in their order from one ledgerto another.

What is claimed is:

1. A. clip for loose-leaf binders, comprising a base, means on said basefor detachw ably connecting the leaves therewith, and separablefastening means on said base for lletchably connecting the clip to thebinder 2. In a Vloose-leaf binder, including a back having aperturestherein, and a clip'for the leaves, comprising al base, a pivoted ring,a

projecting head on the opposite side of the base for engagement throughthe apertures, and a frictional clampingy element engageable over thehead for vdetachably associating the clip with the binder back.

3. In a loose-leaf binder including a back and leaves, a clip forconnecting the leaves to the back, having detachable means of connection with the binder bacln'comprising a separable fastening element.Y
